It makes 0 WM builds less good, thus a nerf to str monster builds. Which i think is good because full agi builds are gimp.
It is a slight buff to specs with high WM, which wont do much because WM in itself doesnt really do much.
People who want to hybrid spec have to use alot of WM to make it work, so 18agi minimum.
All in all i dont think it will do much, since wpf does so little overall.
And if it means less people with ranged sidearms, i will be happy
